LMC7221 Tiny CMOS Comparator with Rail-To-Rail Input and Open Drain Output
General Description
The LM7221 is a micropower CMOS comparator available in the space saving SOT23-5 package.
This makes this comparator ideal for space and weight critical designs. The LMC7221 is also available in the SO-8 package. The LMC7221 is supplied in two offset voltage grades, 5 mV and 15 mV. The open drain output can be pulled up with a resistor to a voltage which can be higher or lower than the supply voltage -- this makes the part useful for mixed voltage systems. For a tiny comparator with a push-pull output, please see the LMC7211 datasheet. n n n n n n Guaranteed specs at 2.7V, 5V, 15V supplies Typical supply current 7 µA at 5V Response time of 4 µs at 5V LMC7221 -- open drain output Input common-mode range beyond V- and V+ Low input current
